Should teens have their parents change their diapers?

Answer 1

Generally speaking, most children should have outgrown the need for diapers long before they reach their teen years.

That being said, if the child/teen suffers from some sort of disability or other condition which prevents him/her from preforming routine tasks (including independent bathroom use), the parents or guardians would find themselves legally obligated to care for the child/teen until their 18th birthday (assuming they are living in the United States).

However, if the teen's continued use of diapers is based solely on personal choice and not health or safety reasons, conventional opinion on modern parenting would suggest requiring them learning to use a toilet like the rest of civilized society.
